The damage or death of an area of the heart muscle (myocardium) resulting from a blocked blood supply to the area. The affected tissue dies, injuring the heart. Symptoms include prolonged, intense chest pain and a decrease in blood pressure that often causes shock.

Gross necrosis of the myocardium as a result of interruption of the blood supply to the area; it is almost always caused by atherosclerosis of the coronary arteries, upon which coronary thrombosis is usually superimposed.

A condition in which the muscles of the heart are killed or damaged because they do not get enough blood and oxygen. Also known as a heart attack, it happens when there is a blockage of the blood vessels that supply the heart and the coronary arteries.

A heart attack. Heart muscle dies as a result of an inadequate blood supply. Often occurs when a blood clot forms in the coronary arteries, reducing the blood supply to the heart, especially when the arteries have been narrowed by cholesterol build-up (atherosclerosis).

The medical term for heart attack. It refers to changes that occur in the heart muscle (myocardium) due to the sudden deprivation of circulating blood. The main change is necrosis (death) of myocardial tissue.

refers to the medical terminology for a heart attack which is damage to the heart muscle as a result of loss of oxygen supply to that muscle; smoking, cholesterol levels, and family history are some of the risk factors for heart disease

Heart attacks result from coronary heart disease (CHD) - blood vessel disease in the heart. A heart attack occurs when the blood supply to part of the heart muscle itself - the myocardium - is severely reduced or stopped.

The medical term for heart attack, which occurs when the blood supply to part of the heart muscle itself â€“ the myocardium â€“ is severely reduced or stopped, resulting in the death of a segment of the heart muscle.

A life­threatening condition caused by complete interruption of blood flow through a coronary artery or bypass graft. This condition requires immediate medical attention. Symptoms include discomfort (pain) or pressure in the chest, arms, jaw or back (usually between the shoulder blades). Other symptoms include shortness of breath, fatigue, weakness or stomach discomfort (indigestion or "heartburn"). If any of these symptoms are felt for more than five (5) minutes and are not relieved by rest (and/or your heart medications), seek medical attention immediately.

An interruption of blood supply to the heart; may be caused by blockage of a heart artery caused by atherosclerosis or a blood clot; MI causes tissue damage to the heart muscle. It may begin with a crushing chest pain that moves to the left arm, neck or upper abdomen, and it may seem like indigestion. Signs of MI are rapid, irregular heart rate, low blood pressure and fever. Emergency treatment may require CPR; commonly called a heart attack.

Death of an area of heart tissue due to a blockage of blood flow to the heart muscle (myocardium). Symptoms may include nausea, shortness of breath, and pain in the chest, arm, or neck. Also called a heart attack.

(MI) Sudden, severe chest pain that occurs when a portion of the heart no longer receives oxygen-rich blood, usually due to total or near-total blockage of a coronary artery by a blood clot formed in an area already narrowed by plaque. The surrounding heart muscle dies and the heart stops working effectively. Also known as a heart attack. A myocardial infarction is part of the acute coronary syndrome.

After one or several heart attacks, scar tissue prevents the heart from working efficiently, leading to a weakening and dilating of the heart chambers (left and right ventricle) and frequently progressing to heart failure. See Heart Attack.

Damage to a portion of the myocardium (heart muscle) as a result of insufficient blood to the heart. Commonly called "heart attack." Nasogastric (NG) tube: An external feeding tube inserted through a patient's nose, down the esophagus, and into a patient's stomach.

Commonly known as a "heart attack", a myocardial infarction refers to changes that occur in the heart muscle due to an interruption in its blood supply. An MI is often the result of a clot that lodges in a coronary artery, resulting in deprivation of oxygen to a portion of the heart muscle (ischemia), and ultimately the death (necrosis) of a portion of the heart muscle, if the oxygen supply is not restored within a few minutes.

Commonly called a "heart attack." Involves irreversible damage to heart tissue/muscle. Insufficient oxygen reaching the heart muscle via the coronary arteries may cause angina, heart attack (myocardial infarction), or even death to the affected area of the heart.

Synonymous with “heart attack”; an area of dead or dying tissue in the heart muscle (myocardium) resulting from insufficient or absent blood flow. “Acute” myocardial infarction describes a heart attack that is in the process of occurring.

(aka heart attack)- is damage or death of an area of the heart muscle, secondary to a decrease in the blood supply to that area. Most myocardial infarctions cause pain, however, some are silent, and occur in the absence of pain (commonly in diabetics).

Commonly known as a heart attack, myocardial infarction is a blockage of a heart artery, caused by hardening of the arteries or by a blood clot. Frequently signaled by severe chest pain that may spread to the left arm, neck or upper abdomen, a heart attack requires immediate emergency medical treatment.

Acute myocardial infarction (AMI or MI), commonly known as a heart attack, is a disease state that occurs when the blood supply to a part of the heart is interrupted. The resulting ischemia or oxygen shortage causes damage and potential death of heart tissue. It is a medical emergency, and the leading cause of death for both men and women all over the world.World Health Organization. http://www.who.int/whr/2004/annex/topic/en/annex_2_en.pdf Annex Table 2: Deaths by cause, sex and mortality stratum in WHO regions, estimates for 2002 The world health report 2004.
